SG-122
The SG-122 (also SU-122 on a German chassis) was a rare Soviet self-propelled gun from World War II. It was created in 1942 by converting captured German Panzer III tanks or StuG III assault guns, into which a Soviet 122mm howitzer (M-30) was installed. Technical data and history Chassis: Captured German Panzer III / StuG III Main armament: 122mm howitzer M-30 Engine: Mostly German Maybach engine (HL 120) Number built: Only about 10 to 21 vehicles Production Use: Due to technical problems, transmission weaknesses, and the difficult supply of spare parts for captured chassis, the project was quickly ended

Brief battle career
The 14 SG-122s that were delivered in January were sent to the Moscow Artillery Center, from where they were transferred to the 1435th Self Propelled Artillery Regiment (SAP), formed on January 1st, 1943. On January 5th, the unit began receiving SU-12 (SU-76) SPGs, followed by the SU-35 (SU-122). On January 28th, the SU-35 were transferred to the 1433rd and 1434 SAPs, which were replaced by SG-122s in early February. The unit’s documents periodically referred to them as SU-35.
As of February 2nd, the regiment had five rearmed Artshturms, and by the 4th, three of them already needed repairs. Documents state that delivery of SPGs from factory #40 was slow, and several of the SPGs arrived with defects. Some of them were so severe, that they needed repairs at the factory.
By February 8th, the number of SG-122s reached seven, five of which were in repairs on the next day. Finally, on February 15th, the number of SG-122s reached sixteen (14 from the factory and two from the reserve training regiment), five of which were in repairs.
The 1435th SAP was sent to the front on February 20th, by which time the number of SG-122s dropped to 12. Four vehicles were given to the SPG Training Center. The 1435th SAP unloaded at the Dabuzha station. SG-122 1002 and 1011 were left along the way. By March 3rd, only eight SG-122s remained combat capable out of 12.
The SPGs trial by combat happened on March 7th, 1943, in battle for the Verkhnyaya Akimovka village. The SPGs supported an attack by the 248th Tank Brigade of the 9th Tank Corps. Seven SU-12s and seven SG-122s went into battle. Three of them were knocked out, and two burned up. The SPGs’ fire destroyed three anti-tank guns, two machinegun nests, and one tank.
On the next day, SG-122 #1003 burned up, #1016 and #1025 were knocked out. On March 9th, the battle for Verkhnyaya Akimovka continued. There were no losses that day, and the SPG crews claimed one anti-tank gun and two MG nests. Lieutenant Koval and gunner Yurin excelled in these battles, claiming two guns, four dugouts, four MG nests, and one car.
The 1435th SAP went into battle on March 14th for the last time. Three SU-12 and four SG-122 SPGs were used to attack the Yasenok village. Two vehicles returned from the fight with insignificant damage, two burned up, and three were knocked out.
The fate of the SG-122 was unfortunate. Nevertheless, the SPG left its mark on Soviet SPG building history. Many solutions developed by factory #592 during its design were later used to design medium SPGs, creating the SU-122. The idea of a loading tray was later used on the SU-152.
The SG-122 was not the last SPG for Sinilshikov. On November 5th, 1942, GKO decree #2477ss organized the Central Artillery Design Bureau, headed by V.G. Grabin. Sinilshikov was included into its staff. The TsKB’s first project was the S-1 SPG, a 76 mm F-34 gun on the PzIII chassis. This vehicle was built in large numbers and deserves its own story.

122-SG from the top. As you can see, there is enough room for five crewmen
Maybe for Event why it was a rare vehycle, maybe Battle Rating 2 or 3.
- Yes SG-122
- No SG-122
More Idears from me
- Vehycle
SU-76 (I)
In the winter of 1941 and during 1942, the Red Army captured numerous German Panzer IIIs. Different models and armaments made direct reuse difficult, partly due to the unreliable supply of ammunition for the German guns. After the first experiences with the SU-76, they quickly wanted to make more of these vehicles operational. The Soviets, therefore, used the German chassis with a new casemate structure and installed the F-34 gun from the T-34/76 tank. The resulting vehicle, which had no secondary armament, was commissioned under the designation SU-76 (I), with the ‘I’ standing for ‘foreign’ (Russian Иностранная, inostrannyy). In total, 201 SU-76(I)s were built. The first deployment was at the Battle of the Kursk Bulge in mid-1943. By early 1944, enough SU-76 Ms were available for all front-line units, and the remaining SU-76 (I)s were assigned to training units.
There would be even a possibility for a German Version

Individual vehicles were recaptured by the Wehrmacht; it is documented that one of these vehicles was used with an additional German commander’s cupola.
A video where both vehycles are shown https://youtu.be/xikSiZCQjy0 please watch more info!
It hase a weaker gun then the first one , then maybe Battle Rating 2 or 1 would be maybe right.
It was a rare vehycle maybe it would not be bad for event?
The Gun
The 76.2 mm (3 in) S1 gun could fire high explosive HE shells, as well as armor piercing rounds. Firing as an artillery gun using HE shells, it had a maximum range of 13.29 km (8.25 miles). Its armor piercing rounds could penetrate 75 mm (2.95 in) of armor plate at a distance of 500 m and 82 mm (3.23 in) at 100 m range, when the armour was at a 90 degree angle. It could not penetrate the front armor of a Tiger tank, but could knock out a Panzer III or IV tank.
